Toyota 4Runner Performance Chips
A Toyota 4Runner performance chip is designed to improve many electronic and mechanical functions by changing the information sent to the 4Runners engine control unit, or ECU. If you are looking to install the 4Runner turbo kit or any other high-performance modifications, you should consider using a performance chip. Used with a programmer, performance chips can greatly increase the potential power of your vehicle.
How does chip tuning work?The term "chip tuning" is used to suggest remapping of the onboard computer, replacing the factory chip for an aftermarket model, buying an entirely new ECU, or piggybacking electronic devices onto the factory ECU. The most common choice for most people who want to increase their vehicles performance is to purchase a performance chip and piggyback it on the factory Toyota computer system.
What is an ECM?The Engine Control Module, or ECM, is what controls the vehicles fuel, air, and spark. These are all must-have components for the car to function. Furthermore, it is the job of the ECM to monitor the numerous sensors on the 4Runner to be sure that everything is running as it should. If the vehicles conditions change for some reason, the ECM will adjust to those conditions in order to keep the entire system running. Additionally, the ECM can be modified by using aftermarket performance chips. Lastly, it should be remembered that the ECM controls only the engines performance and no other part of the car.
Is it complicated to install a performance chip?It only takes 30 minutes or so to install electronic chips as a part of the cars computer system. Add to this fact that you can use programmers to fine tune these chips, tuning your Toyota is easy.
What is a programmer?In the past, mechanics used the three Cs when adding power to an automobile: carburetor, camshaft, and compression. Since the development of better automobile technology, a fourth C has become just as crucial: computers. Once you have modified your 4Runner and installed your chip, performance programmers (also known as a tuner) will become an integral part of keeping your Toyota 4Runner running well.
What horsepower gains you can expect?Without making any permanent modifications to your Toyota 4Runner, you can expect an increase of 35 to 40 horsepower and an added five MPG. This is because the SUVs fuel/air ratio and timing is optimized. Furthermore, these are designed to fit all models of Toyota 4Runner trims: Limited, DLX, Base, SR5, Trail and Sport models featuring 2.4L, 2.7L, 3.0L, 3.4L, 4.0L, and 4.7L engines.
